y = kx, where k is the constant of proportionality.

We need to find k as our first step.

35 = k140

35/140 = k

1/4 = k

We can now find y when x = 70.

y = kx

y = (1/4)(70)

y = 70/4

This fraction can be simplified or reduced more.

The number 2 is the GCF of 70 and 4.

70 ÷ 2 = 35

4 ÷ 2 = 2

Answer:

y = 35/2
